WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 514,616, dated February13, 1894.

Application filed August 16, 1893. Serial No.483,294. No model.)

To all whom it may concern.-

Beit known that I, GEORGE WILLIAM CAMP- BELL, a citizen of the UnitedStates, residing at El Paso, in the county of El Paso and State ofTexas,have invented a new and useful W'atear-Elevator, of which thefollowing is a specification.

This invention relates to water elevators; and it has for its object toprovide an improved water elevator of that character intended to elevatelarge quantities of water from an ordinary well for large ranch use andirrigating purposes.

To this end the main and primary object of the present invention is toconstruct awater elevator which can be easily operated by the directpull of a single animal, which passes and repasses the well during theoperation of raising and lowering the well bucket, and by this meanscontemplates dispensing with the necessity of winding drums orwindlasses and horse powers, which are usually employed in connectionwith water elevators of the character noted.

With these and other objects in view which will readily appear as thenature of the invention is better understood the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated and claimed.

In the accompanying drawingsz-Figure l is a perspective viewof a waterelevator constructed in accordance with this invention, showing the wellin section, and a draft animal hitched to the hoisting or elevator rope.Fig. 2 is a central vertical sectional view of the water elevator. Fig.3 is a vertical sectional view on the line m-os of Fig. 2. Fig. 4 is adetail in perspective of the bucket slide frame. Fig. 5is a similar viewof the bucket.

Referring to the accompanyiny drawings, A represents a well of theordinary construction dug out many desired depth and accommodatin gtherein the vertical and parallel guide bars or rods B. The verticalguide bars B, are suitably secured at their lower ends in the bottom ofthe well, and extending above the top of the well and the well platformC, are connected at their upper extremities by the cross beam D, andsuch. upper projecting ends of the opposite guide bars are securely andfirmly braced to the upper well platform 0, by means of the brace frameE, secured to the guide bars near their upper ends and arising from thewell platform 0. The well platform 0, is located as usual at the top ofthe well, and is provided with a squared or rectangu ar opera ing F,therein, of a width equaling the space between the two vertical guidebars B, and 6c the opening in the well platform is designed toaccommodate the vertically moving slide frame G, which passes throughsaid opening in its ascent and descent. The vertically moving slideframe G, is designed to work between 6 5 the parallel guide bars B, andis of an approximately U -shape. The approximately U-shaped slide frameG, is provided with the opposite Vertical side portions H, which slideat one side or the inner edges of the vertical 7o guide bars B, and thesaid vertical side por-' tions H, are provided at their upper and lowerextremities with the parallel off-standing guide ears or lugs I, whichembrace the op' posite side edges of the vertical guide bars 7 thereofone end of the hoisting or elevating rope K. The slide frame G, whichmoves up and down between the vertical guide bars B, is further providedwith the upper transverse stop rod L, which connects the upper ends of rthe side portions H, below the loop J, and also go with the lowerstationary pivot rod M, which connects the lower extremities vof saidside portions. The said stationary pivot rod M, forms a supporting pivotfor the elongated well bucket N. The well bucket N, is of an 9 5approximately rectangular shape and of a depth sufiicient to carry aconsiderable quantity of water, and the well bucket N, carries thestationary transverse bearing sleeve 0.

The bearing sleeve 0, passes transversely through the bucket N, at oneside of and below the center of such bucket, and loosely fits The saidslide frame B, 8ov

over the stationary pivot rod M, so that the bucket will be free to turnor tilt on said pivot rod, in order to discharge its contents at the topof the well, and by reason of the disposition of the bearing sleeve atone side of and below the center of the bucket, such bucket is normallyoverweighted or overbalanced at one side of its pivotal support, so asto normally hold it in an upright position between the opposite sideportions H, of the slide frame, and is held in such normal verticalposition by the stop shoulders P, formed in the top edges thereof andadapted to engage at one side of the upper transverse stop rod L.

p The well bucket N, is provided in the bottom thereof with an upwardlyopening valve Q, which, when the bucket is lowered into the well, opensupwardly within the bucket so that the latter can readily fill withwater, but which closes immediately upon the ascent of such bucket.After the bucket has been filled with water, the same is hoisted in amanner to-be presently described up to the top of the well and throughthe opening in the well platform 0, until the side trip arm R, engageswith one edge of the well platform or a similar suitably arranged strikeprojection. The said trip arm R, is pivoted at one end on one extremityof the bearing sleeve 0, and has the free end thereof normally projectbeyond one end or side of such bucket, and said trip arm is held initsproper position by means of the keeper loop S, attached to one side ofthe bucket so that the trip arm will freely adjust itself to its properposition after the bucket has tilted back to its normal position.

' The said trip arm normally rests on the stop pin T, projecting fromone side of the bucket near one edge thereof, so that as the trip armengages one edge of the well platform it presses on said stop pin, andthereby causes the bucket to turn or tilt on its pivot and discharge itscontents out of the top thereof and at one side of the well into anysuitable receptacle or trough adapted for its reception. Now it will beapparent that as the bucket is hoisted to the top of the well, thetrip'arm R, will engage under one edge of the well platform and causethe bucket to tilt or drop to one side to discharge its contents, andthe side tilt of the bucket is limited or checked by the transverse stopbar U, secured to one side of the bucket near its bottom, and having theopposite projecting ends thereof adapted to come against one side of theguide bars, thereby holding thebucket checkedin its tilted positionuntil the contents thereof are discharged. The hoisting or elevatingrope K, which is attached at one end to the upper end of the slide frameG, passes over the upper guide pulley V, located above the top of thewell. The guide pulley V, is journaled in a pivoted sheave W, having atone side and the top and bottom thereof the projecting pivot pins X,journaled or bearing in the top of the frame F, and the cross beam D,thereby providing a support for the pulley whereby the same may beturned in any direction during the operation of raising andlowering thewell bucket. The upper end of the hoisting or elevator rope which passesover said pivoted guide pulley, is especially adapted to be attached tothe pommel or horn of a horse saddle Y, fastened to the back of anysuitable draft animal. Now by reason of the specific pivotal support ofthe upper guide pulley, it will be apparent that during the operation ofthe elevator, the horse can pull out to one side of the Well until abucket of water is drawn and discharged, and can then turn and start inan opposite direction and continue in said opposite side direction untilthe bucket has been lowered into the well of its own weight, filled, andagain raised and discharged, thereby avoiding the turning of the animalfrequently.

Many advantages will suggest themselves to those skilled in the art fromthe operation just described.

Changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is
